Rebar Repair of Radial Meniscus Tears: A Reinforced Suture Technique.

The purpose of this paper is to describe the rebar repair as a technique for repair of radial meniscus tears and compare the rebar technique with current techniques used for meniscus repairs. This technique consists of 4 sutures placed with the inside-out technique. First, the vertical mattress reinforcement sutures are placed anteriorly and posteriorly to the tear. Then, 2 parallel horizontal sutures are placed directly in juxtaposition to the vertical sutures, ensuring the needles pass on the side of the reinforcing stitch away from the tear. This technique is less technically challenging than other meniscus repair techniques that require drilling of a transtibial tunnel. Overall, the rebar technique offers a more optimal way for stabilizing the meniscus by using 2 reinforcement sutures that run with the circumferential fibers to help restore the natural hoop stress of the meniscus. Also, the placement of the vertical mattress sutures in the rebar technique offers more direct reinforcement to the horizontal mattress sutures as compared with other techniques, which reduces the risk of pull-out tears.
